Description

Present invention relates to a post foaming gel composition for hair for improving its shine and curl retention, reducing flyaways, and setting.
Gel type of hair styling compositions have been know for sometime and usually used for setting hair into a certain desired shape. Gel types of compositions are usually packed into a jar although there are gels packed in a tube have also been made available for users. Their application onto hair is usually carried out taking certain parts from the jar and first distributing it on hand surface which is followed by transferring the product from hand to hair surface. This way of application is very ineffective and brings largely microbiological contamination which limits the product life. Furthermore, such products are not homogeneously distributed onto hair surface so that hair style retention is also not very optimal all over the whole head.
Foam applications have been know to overcome such difficulties which required usually high concentrations of surfactants and additionally the gelling ingredients blocks release of the compositions from the packaging because of their high viscosity.
Present invention starts from the above mentioned problems and provides solution to the one or more of them.
The inventors of the present invention has found out that a gel composition forming a foam after its release from its packaging is easily applied onto hair homogeneously and hair styled with such composition is put in the desired from homogeneously and the purchased product may be used entirely as no contamination problem exists.
A post foaming get composition is known from EP 876 204 B1 which comprises high level of surfactants and therefore is not favorable as a finish product and especially on wet hair.
EP978271A1 discloses a quick breaking foam composition comprising an alkyl acrylate copolymer. The composition is not a post-foaming gel composition.
Accordingly, present invention is on a post-foaming aqueous gel composition comprising one or more thickening polymer, one or more film forming polymer, one or more polyol, one or more surfactant and one or more C4 - C5 isoalkane which is easily and homogeneously applied onto hair after releasing from its packaging and it improves shine and curl retention of hair, reduces flyaways and has moderately good setting effect on hair.
